Compact-type heat dissipation device for fluorescent color wheel

The invention discloses a compact-type heat dissipation device for a fluorescent color wheel. The compact-type heat dissipation device is characterized in that the compact-type heat dissipation devicecomprises a first heat dissipation fin set, a second heat dissipation fin set and heat pipes; the evaporation sections of the heat pipes are arranged in the first heat dissipation fin set in a penetrating mode, and the condensation sections of the heat pipes are arranged in the second heat dissipation fin set in a penetrating mode; a receding cavity which is sunken towards the inner side is formed in the middle of the first heat dissipation fin set; and the first heat dissipation fin set is arranged over the fluorescent color wheel, and the fluorescent color wheel extends into the receding cavity to be mounted. The heat dissipation device matched with the fluorescent color wheel for heat dissipation uses the heat dissipation mode that heat dissipation fins cooperate with the heat pipes and sufficiently and reason
